[Bug 675337] [NEW] Black screen instead of (gdm) login screen after dist-upgrade.

 

Public bug reported:

Binary package hint: xorg

Got this problem on my ASrock ION 330HT system.
First after a custom kernel build (to get support for my ASrock remote) I got this problem and thought it was related in some way. But the error persists even with the ubuntu kernel.  I found that the GDM log files complains about something missing in DBUS, but i'm clueless about DBUS, so that does not help me. Tried to reinstall a lot of packages. (gconf2*, network-manager, lirc, dbus.) but it did not help. (Was thinking I might have some bit rot on my hard disk.)
Had to give up.. Reinstalled the whole box... Everything worked fine. Got XBMC and my remote working again. Then the last thing to do: dist-upgrade... Did that, and rebooted the machine. Back to same black screen instead of the gdm greeter... 

So a suppose the last dist-upgrade is to blame.

I know, I have one PPA archives enabled, but I see no packages from that archive among the updated packages.
"
Switching to console (ctrl-alt-f1) works, and starting x (startx -- :1) works.. (Needs to use :1 as :0 is occupied by GDM)

I put this bug on xorg, but that's because the guide tells you to do
that. But as there is no errors in the X server log files, I suspect the
error is in either dbus/gconf/apparmor

Any clues?
